Hello! I’m Cassandre, and today on Caramel Loafing, I’m thrilled to share a super easy, wonderfully fresh French citrus cake: the Gâteau moelleux au citron.
This might just be the easiest lemon cake you’ll ever bake.
This easy French lemon cake recipe uses just six ingredients — butter, eggs, flour, lemon, sugar, and baking powder — and the method is simply a matter of mixing. From start to finish, you’ll have this fluffy lemon cake on the table in about 40 minutes.
It’s designed so that anyone can make it using everyday pantry staples. No fancy techniques — just simple steps for a light, crowd-pleasing treat that’s perfect any day of the week.
In France, simple homemade cakes like this are often baked for le goûter, the traditional afternoon snack enjoyed by children and adults alike. A tender citrus cake, sliced and shared with tea or coffee, is a familiar sight in many French kitchens. Recipes like Gâteau moelleux au citron are beloved precisely because they are quick, comforting, and easy to make with ingredients most households already have on hand.
Our version is inspired by the beloved French chef Cyril Lignac, widely known as France’s favorite home cook and a Michelin-starred chef. We’ve slightly adjusted the wet-to-dry ratio and reduced the sugar a bit for a lighter taste.
The first time I baked it, I fell in love with the fresh lemon aroma and the soft, cloud-like crumb. The generous amount of lemon juice provides a subtle tang, while the cake remains tender and moist—you’ll wish you’d discovered it sooner!

Instructions
- Grease your muffin pan with softened butter and dust lightly with flour. Set aside in a cool spot.
- Combine the grated lemon zest with the sugar and rub them together with your fingers until fragrant.
- Sift the flour and baking powder together, then whisk to combine.
- In a mixing bowl, beat the softened butter and lemon sugar on medium speed until pale and fluffy.
- Add the beaten egg in two parts, mixing well each time. The batter may look slightly curdled — this is normal, and the flour will bring it together.
- Add the sifted flour mixture and mix on low speed until just combined.
- Pour in the lemon juice and mix on low speed until smooth. Do not overmix.
- Divide the batter into the muffin cups, filling about 70% full.
- Bake in a preheated oven at 355°F (180°C) for 26–28 minutes, or until the tops are golden. Adjust baking time based on your oven.
- Enjoy plain, dusted with powdered sugar, or topped with a candied lemon slice. Store in an airtight container — 2–3 days at room temp, 5–6 days refrigerated, or freeze up to one month.
- To make candied lemon slices: slice the lemon into 7–8 mm thick rounds and remove seeds.
- Place slices in a pot of cold water, bring to a boil, blanch for 20 seconds, then drain. Repeat twice.
- Return lemon slices to the pot, add water and sugar, and simmer on medium-low until translucent and golden, about 25–30 minutes.

French Lemon Cake FAQs
This easy French lemon cake is ready in just 40 minutes — a cross between a pound cake and sponge cake with a crisp edge and fluffy interior. But a few details can make all the difference! Here are some common questions and tips for success:
What’s the best butter texture for creaming?
The butter should be fully softened but not melted — this is key to achieving the right texture. In colder months, take the butter out well ahead of time. If you’re in a hurry, cut it into small cubes and warm it gently near the oven. A handy trick: fill a bowl with hot water, pour it out, then place the warm bowl upside down over the butter to help soften it evenly. If you’d like to see this trick in action, check out our Honey Butter Toast Recipe video, where I demonstrate the entire process. If the butter melts completely, the cake will be greasy and heavy.
Why does my butter and egg mixture look split?
Don’t worry! In this recipe, the batter often looks a bit curdled because of the high liquid ratio. That’s totally normal. Once you add the flour, it will come together into a smooth, silky batter. No need to panic or add extra flour.
What other pans can I use?
This cake is versatile — you can bake it in muffin pans, madeleine molds, mini loaf pans, or even a classic pound cake tin. Just adjust the baking time if using a larger pan; add an extra 5–10 minutes and check with a skewer or toothpick to ensure the center is cooked through.
How do I unmold the cakes easily?
Use softened butter (not melted) to coat your pans evenly, then dust with flour. This helps the cakes release cleanly and creates a crisp exterior. Let the cakes rest for 5–10 minutes after baking before unmolding so they can shrink slightly — no stuck bottoms!
Can I use other citrus fruits?
Absolutely! This lemon cake recipe also works beautifully with limes, yuzu, grapefruit, oranges, or even a blend. Just adjust the sugar to balance each fruit’s sweetness or tang. This is your go-to adaptable citrus cake.
Why did my lemon cake turn out dense?
A dense lemon cake is usually caused by a few common baking issues. Overmixing the batter can develop too much gluten, making the cake heavy instead of tender. Butter that is too warm or partially melted can also prevent proper aeration during creaming. Finally, make sure your baking powder is fresh — if it has lost its potency, the cake may not rise properly. For the best texture, mix gently and use room-temperature ingredients.
How should I store lemon cake?
To keep your lemon cake fresh, store it in an airtight container at room temperature for up to 2–3 days. If your kitchen is warm or humid, refrigeration is a safer option and can extend freshness to about 5–6 days. For longer storage, wrap the cake tightly and freeze it for up to one month. When ready to serve, let it thaw at room temperature or warm it briefly in a low oven to bring back its soft texture.
